IMPROVEMENT IN LINING PETROLEUM 'BARRE LS,

Specification forming part of Lrttcrs Patent No. 47.363, dab-d April 1B, 1865.

ing the substance derived from the leaves and stems of the Opium! cal (iris or act-us rulgariflor prickly-pear) by the process of boilingthesamc for a sutiicient length of time so'that the liquid, when cool, will be of the consistency of ordinary glue. 1' then mix the samewith whit-- ing, lime, flour, bran, or other material, so as to produce the consistency of common paint, and I then apply it-,\vbcn hot, to the insides of barrels or other vessels, completely saturating the wood and joints with this composition. Aiter its ap 'ilication, as above described, and when nearly cold, 1' apply a cmnposition made of glue, molasses, isinglass, and gum-shellac. This composition I put over the former while it is quite hot, but not boiling, and, being appl ted before the first composition becomes col d, it unites with it, constituting a substance almost as durable and as hard as porcelain, with out the danger of breaking or cracking, and which is not affected by climate.

I do not confine myself to the use of the prickly-pear alone in the production of my first composition, but can use the Parmleria Mom, or other similar plants of analogous properties.

One of the importau from the use of the prtdiminary preparationis found in the fact that by its use the pores of the wood are closed, and the surface of the wood is properly fitted for thei'eceptio11 of the second application,which is bythisineans rendered much more effective and valuable.

Both the first and second compositions herein described maybe i ncorporatedbefore being applied, as well as being se aratclyuscd, as hereinbel'ore provided. I 1

Having thus fully described my said imp rov cment, what I claim as my invention, and desire to secure by Letters Patent, is-

1.. A preparation composed ot the juice of the prickly-pear or other gelatinous plants,-

mixed with lime, plaster-paris, flour, bran, or other similar substances as a priming or preliminary application to the inside of barrels or other vessels, as and for the purposes set forth. 2. The combination of atirst and second at plicatiou to the inner surfaces of barrels or other vessels, as described. l

3. The application of the ingredients herein described when incorporated in one composition and applied substantially as and for the purposes herein setforth.
